摘要
针对克拉玛依新垦绿洲土壤粘重、板结、有机质含量低的实际情况,分别以有机肥、粉煤灰、草炭和沙作为土壤改良材料,测定了不同改良措施对土壤盐分动态变化的影响。研究表明:施肥改良措施对土壤盐分的表聚具有明显的抑制作用。其中,粉煤灰对土壤的改良效果最好,在灌溉的条件下可以将表土层盐分充分淋洗到土壤下层,脱盐率达50%;掺沙次之,有机肥在一定程度上也降低了土壤表层的盐分;草炭与对照措施下土壤的盐分变化规律基本相似,脱盐率大致相同。由此表明,草炭对土壤基本上没有改良压盐的作用。
The organic matter of soil in Karamay is low,and the soil there is sticky and land. In this research the soil improvement measures change on salinity was sured organic fertilizer, coal fly ash, hasty char and sand were appiled as improvement material. The results of this study were summarized as follows ： there were obvious inhibition on soil salinity accumulation. It was very good for dust to improve soil quality, and the salinity could bc adequately flushed into underlayer with irrigation, the rate of taking off salinity is 50% ; Sand is take second place, the organic fertilizer also could reduce salinity of surface layer. The salinity movement rule of the hasty char and the control were similar. The rates of taking off salinity were approximatelv same.
